Massa has been team-mate to both Ferrari drivers and was replaced by Raikkonen over the winter before heading to Williams. Alonso has had the upper hand so far this year at Ferrari, scoring 61 points to Raikkonen's 17, and Massa says that is exactly what he would have predicted.

"The difference between Fernando and Kimi, for me, is not a surprise - I expected it," he said. "Fernando has built the team around him, but also the way he is driving, he is a very strong driver and he managed to put everything on his side as well."

Massa said Raikkonen's only hope is to be at the top of his game all of the time.

"I think to be better than him you have to be 100% and perfect with the car, and Kimi is maybe not 100% ready and perfect with the car. Fernando has also the team for him, so it's not easy."

However, after running third in Monaco until he was hit by Max Chilton, Raikkonen says Ferrari is working hard on getting better results.

"Obviously we need to improve in many areas and we have done a lot of things in many areas to improve already," he said. "We know what we have to do, but those things will not be easy and it just takes time.

We are going forward all the time, but other teams are doing the same also. We know where the weaknesses are, but if solving those was easy everybody would have fast cars. We need to keep working and I'm sure we can get the results we are supposed to get.

"With the feelings we have now, once we get a good feeling on things I'm sure it will be better and we will get the results. We have to keep fighting and be a bit more lucky in the future."
